Phase One XT 23mm lens: Seek extraordinary wide angle

Known for their great resolving power and contrast even at large apertures, the optical design of Rodenstock HR lenses reduces diffraction and colour noise, even at the pixel density of the IQ4 150MP, providing further flexibility to the full frame medium format sensor.

With Rodenstock as a strategic partner, the introduction of these exclusive, digitally integrated lenses is only the beginning of the XT Camera System lens range. Now with the XT 23mm lens, the extremely wide angle 112° field of view provides the capability for impressive single shot, grand scale, images.

The XT lens family now stands with the current 23mm, 32mm, 50mm, 70mm & 90mm lenses. There is a focal length longer than 100mm in the works, more details on this as they come to hand.

At the heart of the XT – Rodenstock HR lenses is the X-Shutter. The X-Shutter is an intelligently integrated and electronically controlled shutter, born out of Phase One’s industrial applications and experience. The X-Shutter is purpose-built for the XT Camera System to allow for finer control in a smaller form factor. Powered by the IQ4, the X-Shutter shares in the ambition of the Infinity Platform for future growth and flexibility.
